Hi - couple of other things. If you are looking for more damage you probably want to go with a Balance Armament out of the kiosk as there are a bunch of good ones there. If you are looking to be defensive with lots of Ward defenses, clockwork paladins would be your best choice for the variety there are in the kiosk.
Also, all the types of hitting power skills such as Balance Dealer, Pain Giver, Balance Giver all rely on Strength, Will and Power attributes. So the higher numbers you have with these attributes the higher potential for max hitting power.
